Application filed May 21, 1908. Serial No. $34,094:.

To all whom it may concern:

Be it known that I, JosEPn WINDLE, a citizen of the United States,residing at Spokane, in the county of Spokane and State of Washington,have invented certain new and useful Improvements in Showl/VindowFasteners; and I do declare the fol lowing to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to the class of show cases, but more particularlyto a fastener for securely holding together and in proper positilon thecontiguous edges of two plates of g ass.

A further object of my invention is to provide a fastener for showcases, show windows or the like, which is so constructed and arrangedthat all tendency to break the glass on tightening the fastener isentirely obviated.

A further object of my invention is to provide a fastener of this classwhich can be applied to plates of glass of any thickness.

A further object of my invention is to rovide a fastener of this classwhich will a ow for any degree of adjustment without pressing againstthe glass or in any way tending to grasp the same.

A further object of my invention is to provide a fastener of this classwhich allows for tightening the connectin bar without causing anypressure on the g ass.

A further object of my invention is to provide a fastener of this classwhich cannot be removed from the outside of the show case or showwindow.

A further object of my invention is to provide a fastener of this classwhich cannot work loose on the inside or outside of the window or showcase by the ar of doors or the like.

With all these objects in view my inven tion consists in the novelconstruction and arrangement of the fastener; and my invention consistsparticularly in the construction which provides for tightening andlocking the connecting bar without exerting any pressure on the glass.

My invention also consists in the construction of the connecting bar andin certain other novel details of construction and in i combinations ofparts, all of which will be i first fully described and afterwardsspecifically pointed out in the appended claims.

Referring to the accompanying drawing: Figure l is a perspective viewshowing the fastener applied to two plates of glass. Fig. 2 is an edgeview showing the fastener in operative position. Fig. 3 is a similarview showing one of the fasteners and a portion of one plate of glass insection. Fig. 4 is a plan and edge view of one of the loose washers, andFig. 5 is an end view of one of the bolts.

Like numerals of reference indicate the same parts throughout theseveral figures in which;

1 and 2 indicate the plates of glass to be fastened together and 3indicates the fastener.

Referring to Figs. 2 and 3 it will be seen that the fastener 3 comprisestwo bolts 4. having heads 5, said bolts being threaded and each boltbeing provided with two flattened sides 6, as clearly shown in Figs. 3and 5. 7 indicates the connecting bar which, as shown in Fig. 1, isconstructed in the form of a loop or link and bent substantially atright angles as shown in Figs. 2 and 3, each arm of the bar 7 straddlingone of the bolts 6 as clearly shown in Fig. 1. 8 indicates a threadedlocking nut which, as shown in Figs. 2 and 3, lies adjacent the innersurface of the glass plates. 9 indicates a loose washer which, as shownin Fig. l, is provided with two transverse grooves 10, the bore oropening 11 of said washer being of such a size as to permit it to slidefreely over the bolt 4. 12 indicates a threaded locking nut adjacent theloose washer 9 and designed to lock said washer on the bolt 4 as shownin Fig. 3.

Having thus fully described the several parts of my invention itsoperation is as folows: After suitable holes have been drilled throughthe glass plates to receive the bolts 4 the first locking nut 8 isthreaded on each of the bolts 4. to such an extent as to prevent allbinding or undue pressure against the inner surface of the plates ofglass as clearly shown in Fig. 2. The connecting bar 7 is then passedover the threaded end of each of the bolts 4 straddling the same, andthe loose washer 9 is then placed on each of the bolts 4 in such mannerthat the transverse grooves 10 in each of said washers re ister with theconnecting bar 7 as clearly s own in Figs. 1 and 3; the second lockingnut 12 being then threaded on each of the bolts as shown in the drawing.The plates of glass being set up in their proper relative positions andthe connecting bar 7 being adjusted in order to maintain the plates intheir proper relative position the first locking nut 8 is adjusted onthe bolt 4 in such manner as to prevent all undue pressure on each ofthe plates of glass. When this has been accomplished and the connectingbar 7 properly adjusted the second locking nut 12 is set up tightlyagainst the loose washer 9, thus looking the connecting bar 7 rigidlybetween the grooves 10 in the loose washer and the contiguous face ofthe first locking nut 8, as

clearly shown in the drawing. it is therefore evident that any degree ofpressure can be applied to hold the connecting bar 7 rigidly in positionwithout exerting any pres-- sure of the first locking nut 8 against theinner surface of the plate of glass. By this construction I am enabledto apply any degree of pressure against the connecting bar 7 withoutdanger of breaking the glass, and to such an extent that the fastenerwill not work loose from the jar of doors or the like; while it is alsoevident that the fastener can not be removed from the outside as it isimpossible to rotate the bolts 4 While the connecting bar 7 is inoperative position thereon, for the reason that the connecting bar 7straddling each of the bolts 4 engages the flat side 6 of each of saidbolts preventing any rotation of the bolts within the connecting bar 7.The transverse grooves 10 in the loose washer 9 registering with theconnecting bar 7 maintain said bar in engagement with the flat sides 6of each of the bolts 4.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent of the United States, is:

1. A fastener of the character described, comprising two bolts, each ofwhich is provided with two flat sides, a locking nut on each of saidbolts, a link shaped connecting bar arranged to pass over the ends ofsaid bolts, a loose washer having two transverse grooves therein.arranged to be passed on each of said bolts, the said grooves in each ofsaid washers registering with the said connecting bar, and a locking nutfor each of said bolts to lock each of said washers firmly in positionand for the purpose of maintaining pressure against the said connectingbar tohold same rigidly in position over each of said bolts.

2. A fastener of the character described comprising two bolts, each ofwhich is provided with two flat sides, a link shaped connecting bararranged to be passed over each ranged to be passed over the end of eachof said bolts, a loosewasher arranged to be passed on'each of said boltsand to engage said connecting bar, and a locking nut for each of saidbolts for engagement with said loose washer on each of said bolts tohold each of said washers firmly in engagement with said connecting bar.7

4. A fastener of the character described comprising two bolts, each ofwhich is provided with a flat side, a connecting bar arranged to bepassed over each of said bolts and to engage said flat side on each ofsaid bolts to lock each of said bolts against rotation, means on each ofsaid bolts for engagement with saidconnecting bar for locking saidconnecting bar firmly in position, and means on each of said bolts forrelieving the objects to be fastened together from the pressure exertedon said connecting bar.

5. A fastener of the characterdescribed comprising two bolts, each ofwhich is provided with a flat side, a connecting bar ar-.

ranged to be passed over each of said bolts and to engage the flat sideof each of said bolts to lock each of said bolts against rotation, andmeans on each of said bolts for engagement With said connecting bar, andfurther means on each of said bolts for securely locking said connectingbar in position. i

6. A fastener of the character described comprising two bolts arrangedto be passed through the objects to be fastened together, a connectingbar for connecting said bolts together, said connecting bar beingarranged to be passed over each of said bolts and to engage same andlock each of said bolts against rotation, means for applying andmaintaining pressure on said connecting bar to hold same rigidly inposition, and means on each of said bolts for relieving the objects tobe fastened together from the pressure applied and maintained on thesaid connect-.

ing bar. v V i In testimony whereof, I affix my signature, in presenceof two witnessesQ JOSEPH 'WINDLE.
